+# Breaking Changes: My Pull Request Was Flagged
+
+A QMK member may have replied to your pull request stating that your submission is a breaking change. In their judgment, the changes you have proposed have greater implications for either QMK, or its users.
+
+Some things that may cause a pull request to be flagged are:
+
+- **Edits to User Keymaps**
+  A user may submit their keymap to QMK, then some time later open a pull request with further updates, only to find it can't be merged because it was edited in the `qmk/qmk_firmware` repository. As not all users are proficient at using Git or GitHub, the user may find themself unable to fix the issue on their own.
+- **Changes to Expected Behavior**
+  Changes to QMK behavior may cause users to believe their hardware or QMK is broken if they flash new firmware that incorporates changes to existing QMK features, and find themselves without a means to restore the desired behavior.
+- **Changes Requiring User Action**
+  Changes may also require action to be taken by users, such as updating a toolchain or taking some action in Git.
+- **Changes Necessitating Increased Scrutiny**
+  On occasion, a submission may have implications for QMK as a project. This could be copyright/licensing issues, coding conventions, large feature overhauls, "high-risk" changes that need wider testing by our community, or something else entirely.
+- **Changes Requiring Communication to End Users**
+  This includes warnings about future deprecations, outdated practices, and anything else that needs to be communicated but doesn't fit into one of the above categories.
+
+## What Do I Do?
+
+If it is determined that your submission is a breaking change, there are a few things you can do to smooth the process:
+
+### Consider Splitting Up Your PR
+
+If you are contributing core code, and the only reason it needs to go through breaking changes is that you are updating keymaps to match your change, consider whether you can submit your feature in a way that the old keymaps continue to work. Then submit a separate PR that goes through the breaking changes process to remove the old code.
+
+### Contribute a ChangeLog Entry
+
+We require submissions that go through the Breaking Change process to include a changelog entry. The entry should be a short summary of the changes your pull request makes – [each section here started as a changelog](ChangeLog/20190830.md "n.b. This should link to the 2019 Aug 30 Breaking Changes doc  - @noroadsleft").
+
+Your changelog should be located at `docs/ChangeLog/YYYYMMDD/PR####.md`, where `YYYYMMDD` is the date on which QMK's breaking change branch – usually named `future` – will be merged into the `master` branch, and `####` is the number of your pull request.
+
+If your submission requires action on the part of users, your changelog should instruct users what action(s) must be taken, or link to a location that does so.
+
+### Document Your Changes
+
+Understanding the purpose for your submission, and possible implications or actions it will require can make the review process more straightforward. A changelog may suffice for this purpose, but more extensive changes may require a level of detail that is ill-suited for a changelog.
+
+Commenting on your pull request and being responsive to questions, comments, and change requests is much appreciated.
+
+### Ask for Help
+
+Having your submission flagged may have caught you off guard. If you find yourself intimidated or overwhelmed, let us know. Comment on your pull request, or [reach out to the QMK team on Discord](https://discord.gg/Uq7gcHh).

+
+At the time of this writing our tests are not very comprehensive. Looking at the current tests and writing new test cases for untested situations is a great way to both familiarize yourself with the codebase and contribute to QMK.

+
+Integration tests can be found in `lib/python/qmk/tests/test_cli_commands.py`. This is where CLI commands are actually run and their overall behavior is verified. We use [`subprocess`](https://docs.python.org/3.5/library/subprocess.html#module-subprocess) to launch each CLI command and a combination of checking output and returncode to determine if the right thing happened.

+## Unit Tests
+
+The other `test_*.py` files in `lib/python/qmk/tests/` contain unit tests. You can write tests for individual functions inside `lib/python/qmk/` here. Generally these files are named after the module, with dots replaced by underscores.

+# Custom Matrix
+
+QMK provides a mechanism to supplement or replace the default matrix scanning routine with your own code.
+
+The reasons to use this feature include:
+
+* Extra hardware between the keyboard's switches and MCU pins
+  * I/O multiplexer
+  * Line decoder
+* Irregular switch matrix
+  * Simultaneous use of `COL2ROW` and `ROW2COL`
+
+## Prerequisites
+
+Implementing custom matrix usually involves compilation of an additional source file. It is recommended that for consistency, this file is called `matrix.c`.
+
+Add a new file to your keyboard directory:
+```text
+keyboards/<keyboard>/matrix.c
+```
+
+And to configure compilation for the new file, add this to your `rules.mk`:
+```make
+SRC += matrix.c
+```
+
+## 'lite'
+
+Provides a default implementation for various scanning functions, reducing the boilerplate code when implementing custom matrix.
+To configure it, add this to your `rules.mk`:
+
+```make
+CUSTOM_MATRIX = lite
+```
+
+And implement the following functions in a `matrix.c` file in your keyboard folder:
+
+```c
+void matrix_init_custom(void) {
+    // TODO: initialize hardware here
+}
+
+bool matrix_scan_custom(matrix_row_t current_matrix[]) {
+    bool matrix_has_changed = false;
+
+    // TODO: add matrix scanning routine here
+
+    return matrix_has_changed;
+}
+```
+
+
+## Full Replacement
+
+When more control over the scanning routine is required, you can choose to implement the full scanning routine.
+To configure it, add this to your rules.mk:
+
+```make
+CUSTOM_MATRIX = yes
+```
+
+And implement the following functions in a `matrix.c` file in your keyboard folder:
+
+```c
+matrix_row_t matrix_get_row(uint8_t row) {
+    // TODO: return the requested row data
+}
+
+void matrix_print(void) {
+    // TODO: use print() to dump the current matrix state to console
+}
+
+void matrix_init(void) {
+    // TODO: initialize hardware and global matrix state here
+
+    // Unless hardware debouncing - Init the configured debounce routine
+    debounce_init(MATRIX_ROWS);
+
+    // This *must* be called for correct keyboard behavior
+    matrix_init_quantum();
+}
+
+uint8_t matrix_scan(void) {
+    bool matrix_has_changed = false;
+
+    // TODO: add matrix scanning routine here
+
+    // Unless hardware debouncing - use the configured debounce routine
+    debounce(raw_matrix, matrix, MATRIX_ROWS, changed);
+
+    // This *must* be called for correct keyboard behavior
+    matrix_scan_quantum();
+
+    return matrix_has_changed;
+}
+```
+
+And also provide defaults for the following callbacks:
+
+```c
+__attribute__((weak)) void matrix_init_kb(void) { matrix_init_user(); }
+
+__attribute__((weak)) void matrix_scan_kb(void) { matrix_scan_user(); }
+
+__attribute__((weak)) void matrix_init_user(void) {}
+
+__attribute__((weak)) void matrix_scan_user(void) {}

-!> Warning: This OLED Driver currently uses the new i2c_master driver from split common code. If your split keyboard uses I2C to communicate between sides, this driver could cause an address conflict (serial is fine). Please contact your keyboard vendor and ask them to migrate to the latest split common code to fix this. In addition, the display timeout system to reduce OLED burn-in also uses split common to detect keypresses, so you will need to implement custom timeout logic for non-split common keyboards.

We have added a define, `OLED_DISPLAY_128X64`, to switch all the values to be used in a 128x64 display, as well as added a custom define, `OLED_DISPLAY_CUSTOM`, that allows you to provide the necessary values to the driver.

- OLED displays driven by SSD1306 drivers only natively support in hard ware 0 degree and 180 degree rendering. This feature is done in software and not free. Using this feature will increase the time to calculate what data to send over i2c to the OLED. If you are strapped for cycles, this can cause keycodes to not register.

For example, in the 128x32 implementation with a `uint8_t` block type, we have a 64 byte block size. This gives us eight 8 byte blocks that need to be rotated and rendered.
